“…The diffractograms reveal that pretreatment processes could enhance the crystalline regions of CP. The characteristic peaks of cellulose I at 2θ = 14.6, 16.4, 22.6, and 34.5°, corresponding to the 11̅0, 110, 200, and 004 crystallographic planes, respectively, , were observed in all samples. Based on Segal’s equation, the CrI values of CP increased from 48.9% (untreated CP) to around 59.8% after the MW-NADES pretreatment.…”

The efficient pretreatment of lignocellulosic biomass is essential for cellulose valorization. This work investigated the fractionation efficiency of the pretreatment process based on natural acidic deep eutectic solvent (NADES) for isolating cellulose-rich materials (CRM) from coffee parchment (CP). The results showed that NADES, composed of choline chloride, oxalic acid, and water in a 2:2:1 molar ratio, was the most efficient solvent for CP fractionation. The sequential pretreatment using NADES under microwave heating (MW-NADES) at 130 °C for 15 min, followed by a two-step alkaline hydrogen peroxide (AHP) process, could maximize the removals of hemicellulose (99.6%) and lignin (97.7%) from CP, leading to production of the CRM with 86.1% cellulose content. This process generated a rough, fractured surface and promoted microfibril disassembly observed in the pretreated fibers. As a result, the CRM exhibited a highly crystalline structure and good thermal stability. Furthermore, the results also highlighted the successful transformation of the isolated CRM to nanofibril networks having a diameter of less than 10 nm and a length of several hundred nanometers. Overall, this work suggests that the sequential MW-NADES and AHP pretreatment could be considered an effective approach in isolating high-purity cellulose from CP, potentially a sustainable source for nanocellulose production.

ILs also act as nano-welding agents by forming a disordered structure on the surface of cellulose, connecting and recombining into a dense network, by which the crystallinity and degree of polymerization are reduced.…”

The development of cellulose‐based hydrogel has occupied a pivotal position in almost all walks of life. However, the native cellulose can not be directly used for preparing hydrogel due to the complex non‐covalent interactions. Some literature has discussed the dissolution and modification of cellulose but has yet to address the influence of the pretreatment on the as‐prepared hydrogels. Firstly, the "touching" of cellulose by derivative and non‐derivative solvents was introduced, viz., the dissolution of cellulose. Secondly, the "conversion" of functional groups on the cellulose surface by special routes, viz., the modification of cellulose. The above‐mentioned two parts were intended to explain the changes in physicochemical properties of cellulose by these routes and their influences on the subsequent hydrogel preparation. Finally, we summarized the “reinforcement” of cellulose‐based hydrogels by physical and chemical techniques, viz., improving the mechanical properties of cellulose‐based hydrogels and the changes in the multi‐level structure of the interior of cellulose‐based hydrogels.

“…Lignocellulosic biomass (LC), one of the most abundant and inexhaustible natural resource, is composed from cellulose, hemicellulose and lignin and it has a complex, rigid structure due to the covalent bonds that are established between these biomacromolecules [1]. Lignin acts as a "glue", linking hemicellulose and cellulose through ester bonds (by intra-and intermolecular bonds) and hydrogen bonds, respectively [2,3].…”

Lignocellulose material is the main natural resource for the pulp and paper industry, and for its application the material should have a degree of whiteness as high as possible. For this reason, different bleaching treatments were applied during time. In this paper, the photobleaching induced by solar light of a lignocellulosic biomass using NaClO was studied. The colorimetric measurements, UV spectra absorption, and FTIR spectra changes are evaluated and discussed in this paper. The changes of L*a*b parameters can be considered a proof of the reactions generated by hypochlorite radicals during solar light exposure, leading to a biomass whitening.
